COOLER FOR WATER AND @THEIR UQUIDS.

JPECIFCATION forming, pari; of Letters Patent No. 321,666, dated duly '7, 1885.

Application tiled April i8, lS.

To all whom, it may Concern.Y

Be it known that I, JOHN AMN DRnLznN, of Peoria, in the county OtPeoria, in the State of Illinois, have invented an Improved Cooler; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the annexed d rawings, making` apart of this specification, in which. like letters of reference refer to like parts,and in which- Figure l represents a central vertical section of the invention; Fig. 2, a plan view ofthe saine with cover removed; Fig. 3, a horizontal section at X X in Fig. l.

This invention is designed, mainly, for cooling gelatine solutions and other emulsions used in photography; but it is equally applicable to the reduction of the temperature ot' drinking-water and for other similar purposes.

The cooler consists ofthe liquid-receptacle, a double-rimmed cover for holding,` the ice and distributing,` the melted Water thereof to the exterior of the said liquid-receptacle, and an enveloping-vessel for protecting said receptacle and ice from the surrounding,` atmosphere and i'or receiving,` the melted water.

In the drawings, A is the liquid-receptacle or reservoir; B, the doublerimmed cover for said reservoir, forming the ice-box. G is the protecting-ease enveloping said reservoir and ice-box, and D is the cover for said case. To increase the non et nductibility of the walls of said ease C, I usually make them double, as shown in the drawings, and jli in the interstices with a cemented mixture of asbest us and oat-hulls. In ,the cheaper iormsof my cooler, however, I construct the said case of earthenware, having its walls solid. As a means of enabling the cover I) to rest air-tight upon the case, corresponding annular `grooves, E', are formed in the contiguous parts of the case and cover, and in said groove Eof the ease is laid a rubber ring, E, circular in erosssection. W'hen the cover I) is placed upon the case C, said ring enters the annular groove E oi" said cover and entirely closes the junction. The

reservoir A is suiiiciently smaller in diameter than the interior of the ease C to provide an annular space thereat, and said reservoir is made to keep in place therein by means ofthe ribs F, secured to the exterior of said reservoir or formed as a part thereof.

To keep (No model.)

the bottoni o" said reservoir as far from the bottom of the ease as is necessary to allow of a sufficient circulation of air and water therebetween, a crown-shaped iiange, G is affixed to the under side or bottoni ot' said reservoir. The serrations of said [lange support the reservoir, and the spaces between them permit the desired circulation of air and water. The upper rim ofthe ice-box B almost touches the under side ofthe cover D, and the diameter of the same is but a little smaller than that of the interior of the ease C. This rim and the bottom E* form the ice box, into which is placed the ice, by which and the water melting,- therefrom the caloric of the reservoir A and its contents is absorbed. In the bot-tom B2, at the annular portion that juts beyond the reservoir A, I make a series of perforations, I'I, through which, as the ice melts, the water therefrom can pereolate into the space below.

In many places, and, in fact, everywhere, it is diiiieult to procure ice of whose lfreedom from contaminating influences we can be perfectly assured. It is therefore important that the ioe in the ice-box and the water therefrom shall be entirely shut away from the drinking-water or other contents of the reservoir A. To do this the under side of the bottom of the ice-box is provided with the rim It, adapted to fit snugly about the upper edge of the reservoir. At the lower edge oi' said rim It, I form the frusto-conical vI'lange K, which, by its shape, makes a shallow basin,into which drips the water from the perforations H. Through said iiange K, at its lowest line, is another series of perforations similar to those in the bottom B2. The water caught in said basin and percolating through its perforations drips down along the sloping under side thereof to the reservoir A, and so down the exterior surface of the saine until it reaches the bottom of the ease C. Here it can be allowed to accumulate, if desired; or it may be permitted to pass out through the drip-pipe L. By means of the catch-basin formed by the ilange Ii, sediment is retained that might otherwise accumulate. in the ease. I often form two or more pockets, I?, in the ice-box B, as shown in Figs. l and 2, the bottoms of which are sufficiently above the perforations H to permit the unimpeded access thereto of the ICO water. In said pockets can be placed any small articles-such as bottles of' wine and the like-which itlnay be desired to cool. Apart ofthe upper edge of each pocket P is turned over somewhat to form handles by which to lift the ice-box from its place. rPhe cooled drinking-water is drawn off from the reservoir A through the valve M. NVhen it is wished to -remove the reservoir A to enable it to be cleansed, it is necessary to displace the said valve M. To do this the inner end of the stein of the sameis screw-threaded and screwed into the boss A of said reservoir. The. elastic washer M enables the passage of said stem through the wall ofthe case C to be closed water-tight. By unscrewing and removing the s'aid valve stem there remains nothing to hinder the reservoir from being taken out.

In addition to using this invention for a cooler, I find it almost equally applicable for use as a plate-cleaner in photography. The only changes that would be required would be that of perforating the bottom of the reservoir A. The soda or other 1naterial,whose slow dissolving replenishes the strength of the cleansiugsolution in the case and rcservoir,is placed in the box B. Filtering-cotton may be placed in the basin K to more thoroughly prevent anything but the clear alkali or acid solutions from passing down into contact with the glass plates to be cleansed. Such alkali or acid solution enters the reservoir A 'through the perforations in its bottom, leaving whatever sedimentary matter upon the bottom of the case that might have escaped the filter. In removing the reservoir A and its contents the alkali or acid flows out therefrom through the perforated bottom.

If desired,V the reservoir A may be divided by suitable partitions into two or more compartrnents.

In using this cooler for refrigerating gela.- tine emulsions I generally employ a glass bottle Ato hold said emulsion and insert said bottle into the reservoir.

In constructing the case C, I generally form the same from sheets of felt cemented together with a thick interlying mixture of charcoal, oat-hulls, and asbest-us, suitably cemented together.

C is the outer layer of felt; C2, the inner sheet; and C, the interlying mixture of cemented charcoal, oat-hulls, and asbestus.

V is a vent-pipe to permit the access of air to the reservoir A, in order to enable the water contained therein to readily run therefrom through the valve M.

Vvlhat I claim as my invention, and for which I desire Letters Patent, is as follows, to wit:

l. The combination, ina cooler, of the outer case, the inner reservoir, and the ice-box fitting within said case upon said reservoir, and having the series of perforations through the portion ofthe bottom of said ice-box jutting beyond said reservoir, substantially as and for the purpose specified.

2. vThe combination, in a cooler, of the outer case, the inner reservoir having the crownshaped supportingange and the vertical ribs, and the ice-box fitting within said case upon said reservoir, and having the series of perforations through the portion 0xff thepbottom of said ice-box jutting beyond said reservoir, substantially as and for the purpose specified.
